WINDMILI..

SPECIFICATION forming part of Letters Patent No. 698,299, dated April 22, 1902.

Application filed February 5, 1902- Serial Noi 921694g y(N0 111,0013

1'0 @ZZ whom it may concern: l. Beit known that I, GRANT S. LOWELL, a citizen of the United States,residing at Salina,

in the county of Saline and State of Kansas,v

have invented a new and useful Windmill,

of which the following is a specification.

The invention relates to improvements in windmills.

The object of the present invention is to improve the construction of windmills and to provide a simple and comparatively inexpensive one of great strength and durability in which the wind-wheel will be hung in the center of the windmill and which willA afford yielding` means for transmitting the power of the wind-wheel to a pump-rod.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed ont in the claims hereto appended.

In the drawings, Figure `1 is-a side elevaj tion of a windmill constructed in accordance with this invention. Fig. 2 is a front elevation of the same. Fig. 3 is a detail sectional view on the line 3 3 of Fig. 1. Figs. 4 and 5 are detail sectional views on the line L 4 and 6 5 of Fig. 2.

Like numerals of reference designate corresponding partsin all the figures of the draw* ings. y

1 designates a rotary frame consisting of an approximately U-'shaped body portion and a depending tubular stem 2', which is journaled in suitablebearings of a tower 4, and the said bearings `are preferably provided withvballs or other antifriction devices, as clearly shown in Fig. 1 of the drawings. The sides ofthe U-shaped body portion of the rotary frame have their upper portions bent ign-- ward and downward tojprovide a pair of depending arms 5, having vtheir lower ends bi,- furcated for the reception of an oscillatory wind-Wheel-carrying frame 6. The windwheel-carrying frame 6 is approximately elliptical, being provided with parallel. sides and roundedends, as clearly shown'in Fig. 1, and it has an arm-or Vshank 7 at its llower end for the reception of an adjustable WeightS for the purpose hereinafter described. The oscillatory frame, which is angularly bent to arrange its upper portion at an inclination when its lower portion is substantially verti cal, as shown in Fig., 2, is provided with upper bearing-openings; 9 for the reception of the pivots for connecting the sides of the frame tothe depending arms, and the said oscillatory frame is also provided Vat points Vbelowthe upper bearings with lower bearing-v openings 11 to receive the wind-wheel shaft 12, uponnwhich the wind-wheel 13 is mounted. The wind-wheel 13, which Amay be of any desired construction, faces the windand is held in the wind by a vane 14, secured to one side of the 4rotary frame, at the bottom thereof, as clearly'shown in Fig. 1.

The wind-wheel shaft 12 is extended beyondthe sides of Mthe elliptical wind-wheelreceiving frame andA has keyed or` otherwise i secured, to it a pair of pinions 15, which are arranged Within and mesh with internal gears 16, located within the spaces between the depending arms and the sides of the frame and mounted on short shafts 17. The short shafts 17, which may form vthe pivots for the oscillatory frame, are journaled in suitable bearings 18 ofthe sides of the U-shaped frame and eX- tend inward and outward therefrom, being provided at their outer ends with eccentric connections 19 for communicating .motion to a verticallywreciprocating frame 2 0. lThe pinions are arranged within theinternal gears and are normally held at points nearthe' bottom of the same, as illustratedin Fig. 42,0f, the accompanying drawings, by the weight of .fthe windwheel, which is located at one i side tof the pivotalv point of the oscllatoryframe ;.but when the force of the wind increases and the rotation of the wind-wheel iscorrespondingly increased this increased'velocity ofl the windwheel will cause the pinions to move upward and partially revolve around the pivot of the oscillatory frame. This partial revolution of the pinions within the internal geanwill cause lan Aupward movement of the lower arm or portion of the oscillatory frame and aconsequent lifting of the wind-wheel. The weight 8, which isgadjustably secured to the shank or A,arm 7 by a clamping-screw 21, isv adapted to IOC the inner end of the arm or shank. Any other form of gearing may be employed; but the internal gears are preferable,for the reason that the arrangement of the pinions Within them practically relieves the pivots of the oscillatory frame of strain, and the gearing of the windmill is balanced at opposite sides and evenly supported and is held against any lateral or twisting movement.

The eccentric connection 19 preferably consists of a disk having a Wrist-pim'and the oscillatory frame 20, which is approximately U-shaped, consists of a pair of upwardlyextending arms connected at their upper ends to the Wrist-pins and extending through slots 22 of the tubular stem of the` rotary frame and connected with a rod 23. The rod 23 is suitably con nected with a pump-rod,and When the Windmill is operated the pump-rod will be vertically reciprocated; but motion may be communicated to any other apparatus or device, as Will be readily understood.

The weight will not have to be arranged as close to the outer end of the shank orarm of the oscillatory frame when the Windmill is connected to a short light pump-rod as it Will When it is connected to a long and heavy pump-rod, and it will be apparent that the parts may be readily adjusted to enable the Windmill to operate smoothly pump-rods of diiferent lengths.

lVhat I claim isl. In a Windmill, the combination of a rotary frame, an oscillatory frame mounted on the rotary frame, a wind-Wheel eccentrically mounted on the oscillatory fran1e,\vhereby its Weight will resist any oscillatory movement of the same, and gearing mounted on the said frames for communicating motion from the Wind-Wheel, one of the gears being arranged to partially revolve around the other, substantially as and for the purpose described.

2. In a Windmill, t-he combination of a main frame, an oscillatory frame mounted on the mainframe,aWind-Wheeleccentricallymounted on the oscillatory frame, a gear mounted on the main frame, and a pinion connected with the Wind-wheel and carried by the oscillatory frame and meshing with the said gear and adapted also to revolve partially around the same, whereby the oscillatory frame will be swung upward and caused to lift the Wind- Wheel, substantially as described.

3. In a Windmill, the combination of a main frame, an oscillatory frame mounted on the main frame, a Wind-Wheel arranged eccentrically on the oscillatory frame, gears mounted on the said frames, the gear of the oscillatory frame being arranged to partially revolve around the other gear, whereby the oscillatory frame Will be actuated to lift the wind-Wheel, and an adjustable Weight carried by the oscillatory frame, substantially as and for the purpose described.

4. In a Windmill, the combination of a main frame, an oscillatory frame of approximately elliptical shape mounted on the main frame and arranged normally in an upright position and provided with an adjustable weight, a wind-wheel eccentrically mounted on the 0scillatory frame and arranged below the pivotal point thereof, and gearing connected with the said frame, one of the gears being arranged to revolve partially around the other, substantially as described.
